Sita SMP Medium Pressure Range UV System (40 to 1200 m3/hr)

Sita SMP Medium Pressure Range

The Medium Pressure (SMP) UV system emits an UV-C irradiation between 200 and 600 nm; these waves length cause an alteration of some chemical links present among nucleotids so that the information contained and conveyed by DNA of every organism present in the water change.These alterations lead to the cellular death and so to the bacteriological elimination.Moreover thanks to this multispectrum wavelength of medium pressure lamps the UV unit has the ability to break chemical bonds, and have a good reduction of unwanted chemicals in water. This photolysis process has a lot of application in swimming pools (reduction of combined chlorine) and process water (de-chlorination, de-ozonation, TOC reduction)The disinfection system has a physical working principle and not chemical. Nothing is added to, not taken away from water; in this way there is no formation of undesired by-products even in case of overexposure, in the full respect of environment.

The. UV-C systems are composed by: - Stainless steel reactor that contains the special germicidal lamps- Control panel, made in compliance with the CE standard

Stainless steel reactor:

The UV reactor is totally in stainless steel 316L internally/externally polished; the stainless steel of itschemical/physical characteristics is particularly suitable for the treatment of primary waters, and beingpolished also in the internal part it is completely without porosity that could favour the keeping of spores.The special UV reactor configuration guarantees a correct contact time, water speed decrease when it arrives in the special radiation area and then returns at original speed at the outlet flangeTo make the maintenance and inspection operations easier the chamber is openable at the lamp side.

Manual cleaning system (standard)

SITA manual cleaning system is standard on all the models.It consist in a rack with special teflon wiper that cleans the quartz sleeve going up and down. The cleaning operation can be done by the operator during the normal system working

Automatic cleaning system RA (optional)

SITA automatic cleaning system is available on all the models (not on model SMP 6)It consist in a rack with special teflon wyper that cleans the quartz sleeve going up and down. This movement is given by a programmable SITA UV cube monitor that moves a motor shaft placed on theUV reactor. Time and days of the cleaning can be easily set on site.

Chemical cleaning system (optional)

SITA chemical cleaning system is available on all the models and can be used together the automatic RA system. It consist in a special tank (depending from UV reactor volume) with pump motor on the top connect/4 SMP Series to the UV reactor. In this way the chemical product (depends from Pollution) will clean not only the quartzes but the whole reactor.This cleaning system is recommended on all the UV of this Series and will integrate the automatic wiping (if present).

Lamp power regulation (optional)

The SMP Medium Pressure UV systems can have a lamp power regulation in order to have an optimized energy consumption. SITA SMP unit need a 4/20 mA input from an external instrument in order to change automatically the lamp power following these parameters:
